Product details
Overview
LMV832MM/NOPB from Texas Instruments is a dual-channel, rail-to-rail output, CMOS-input operational amplifier optimized for EMI-hardened signal conditioning in precision sensor interfaces and portable electronics. It operates from 2.7 V to 5.5 V, draws 240 µA per channel, delivers 3.3-MHz gain-bandwidth, 2 V/µs slew rate, and achieves 120 dB EMI rejection at 2.4 GHz - enabling robust operation near RF sources like cellular transceivers and Wi-Fi modules.
For engineers reviewing the LMV832MM/NOPB datasheet, LMV832MM/NOPB pinout, LMV832MM/NOPB application, or LMV832MM/NOPB equivalent, key selection criteria include its ultra-low input bias current (0.1 pA), −40°C to +125°C operating range, 1-mV max input offset voltage, and validated stability with up to 200-pF capacitive loads in space-constrained industrial and automotive sensing designs.
Technical Context
The LMV832MM/NOPB implements a CMOS input stage with rail-to-rail output swing and an input common-mode range extending to ground, supporting single-supply operation in low-voltage systems. Its unity-gain stable architecture maintains ≥65° phase margin across temperature and supply voltage variations.
EMI hardening is achieved via on-die filtering and layout techniques that suppress RF-induced input offset shifts - verified by EMIRR measurements of 120 dB at 2.4 GHz and 110 dB at 1.8 GHz - making it suitable for analog front-ends in noisy environments without external RF mitigation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 5.5 V - enables direct integration into 3.3-V and 5-V microcontroller-based sensor nodes. |
| Supply Current per Channel | 240 µA - supports battery-powered devices with multi-year runtime in always-on monitoring applications. |
| Input Offset Voltage | ±1 mV max - ensures ≤0.1% error in 1-V full-scale pressure or temperature sensor outputs. |
| Gain-Bandwidth Product | 3.3 MHz - supports closed-loop bandwidths >1 MHz in unity-gain buffers for high-speed ADC drivers. |
| EMI Rejection Ratio | 120 dB at 2.4 GHz - rejects cellular/Wi-Fi interference without external ferrite beads or RC filters. |
| Slew Rate | 2 V/µs - preserves fidelity of fast transient signals (e.g., piezoelectric shock detection) without distortion. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial control cabinet deployment. |
Pinout & Package
The LMV832MM/NOPB is housed in an 8-pin VSSOP package (3.00 mm × 3.00 mm), optimized for thermal performance and PCB area efficiency in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Channel A output - rail-to-rail swing supports full dynamic range utilization with 3.3-V ADCs. |
| 2 | IN A– | Inverting input for Channel A - high-impedance CMOS node minimizes loading on high-Z sensors. |
| 3 | IN A+ | Noninverting input for Channel A - accepts signals down to ground, enabling single-supply transducer interfacing. |
| 4 | V– | Negative supply - tied to GND in single-supply configurations; supports split-rail operation if needed. |
| 5 | V+ | Positive supply - accepts 2.7–5.5 V; PSRR of 93 dB suppresses supply noise coupling into signal path. |
| 6 | IN B– | Inverting input for Channel B - electrically isolated from Channel A to prevent crosstalk in dual-sensor systems. |
| 7 | OUT B | Channel B output - independent output stage allows simultaneous driving of separate signal chains. |
| 8 | IN B+ | Noninverting input for Channel B - identical DC and AC specs to IN A+ for matched dual-channel performance. |
Key Features
| Feature | Design Value |
|---|---|
| EMI-hardened architecture | 120 dB rejection at 2.4 GHz eliminates need for external RF shielding in handheld medical or IoT devices. |
| Rail-to-rail output swing | Output drives within 6 mV of rails at 10-kΩ load - maximizes SNR when interfacing with 12-bit+ SAR ADCs. |
| 0.1-pA input bias current | Enables use with high-impedance pH electrodes, photodiodes, and piezoelectric elements without signal loss. |
| Stable with 200-pF capacitive load | Drives long traces or ADC input capacitance directly - avoids instability-induced oscillation in layout-constrained PCBs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV822MM/NOPB | Lower GBW (1.5 MHz), higher supply current (160 µA/channel), no EMI hardening | Not suitable for RF-noisy environments; limited bandwidth for fast sensor signals | Select only if EMI immunity is not required and cost is primary constraint |
| TLV9062IDGKR | Higher GBW (10 MHz), lower input offset (0.3 mV), but only 85°C max ambient rating | Unqualified for under-hood or industrial high-temp deployments | Prefer for high-speed, room-temperature consumer electronics where thermal margin is sufficient |
Compared with LMV822MM/NOPB and TLV9062IDGKR, the LMV832MM/NOPB uniquely balances EMI resilience, wide temperature operation, and low power - making it the only choice among the three for automotive cabin sensors or industrial field transmitters exposed to cellular/Wi-Fi interference.

FAQ
What is the maximum capacitive load the LMV832MM/NOPB can drive while remaining stable?
The LMV832MM/NOPB maintains unity-gain stability with capacitive loads up to 200 pF, as confirmed in TI's datasheet Figure 25 and Section 7.4. This capability allows direct connection to ADC inputs or long PCB traces without external isolation resistors or compensation networks - simplifying layout and reducing bill-of-materials count in compact sensor modules.
Does the LMV832MM/NOPB support true single-supply operation with input voltages down to ground?
Yes, the LMV832MM/NOPB features an input common-mode voltage range that includes ground (−0.1 V to V+ − 1.2 V at 3.3 V), enabling true single-supply operation. This allows direct interfacing with grounded transducers such as resistive bridges or thermistors without level-shifting circuitry - critical for low-voltage battery-powered systems.
What is the measured EMI rejection ratio of the LMV832MM/NOPB at 900 MHz?
The LMV832MM/NOPB achieves an EMI rejection ratio (EMIRR) of 90 dB at 900 MHz, as specified in Table 6.5 of the SNOSAZ6C datasheet. This value reflects suppression of RF-induced input offset voltage shifts under 100-mVPEAK RF injection, confirming robustness against GSM and ISM-band interference in mobile and wireless infrastructure applications.
Can the LMV832MM/NOPB operate reliably at 125°C ambient temperature?
Yes, the LMV832MM/NOPB is fully specified and production-tested over −40°C to +125°C ambient temperature. Electrical characteristics including input offset voltage (±1.23 mV), supply current (≤580 µA), and output swing are guaranteed across this range - qualifying it for under-hood automotive, industrial motor control, and aerospace avionics applications.
Is the LMV832MM/NOPB pin-compatible with other dual op-amps in the VSSOP-8 package?
No, the LMV832MM/NOPB has a non-standard pinout: OUT A (pin 1), IN A– (pin 2), IN A+ (pin 3), V– (pin 4), V+ (pin 5), IN B– (pin 6), OUT B (pin 7), IN B+ (pin 8). It is not pin-compatible with industry-standard dual op-amps like the LM358 or TLV2372 - PCB layout must follow TI's DGK package diagram to ensure correct signal routing.
